“…The β-glucosidase activity is strongly related to the chemical composition of the host plant. Changes in the activity of GST and β-glucosidase were observed as a result of changing the host from primary to secondary in R. padi [75]. Similar relationships were observed in C. tujafilina after changing the host plant [71].…”

Thermal stress in living organisms causes an imbalance between the processes of creating and neutralizing reactive oxygen species (ROS). The work aims to explain changes in the aphid–host plant interaction due to an increase in temperature. Tests were carried out at three constant temperatures (20, 25, or 28 °C). Firstly, changes in development of Macrosiphum rosae were determined. Secondly, the activity of enzymatic markers (superoxide dismutase (SOD), catalase (CAT), glutathione S-transferase (GST), β-glucosidase, polyphenol oxidase (PPO), and peroxidase (POD)) in aphid M. rosae tissues and host plant were analyzed at all temperatures. An increase in temperature to 28 °C had a negative effect on the biology of M. rosae by shortening the period of reproduction and longevity, thus reducing the demographic parameters and fecundity. Two stages of the aphid’s defensive response to short-term (24–96 h) and long-term (2 weeks) thermal stress were observed. Aphid defense responses varied considerably with temperature and were highest at 28 °C. In turn, for the plants, which were exposed to both abiotic stress caused by elevated temperature and biotic stress caused by aphid feeding, their enzymatic defense was more effective at 20 °C, when enzyme activities at their highest were observed.

“…The increase in GST activity is an essential indicator of the adaptation of insects to changes in xenobiotics, including phenols, present in plants [ 17 ]. Changes in β-glucosidase and GST activity were noted in migration from primary to secondary host of winged R. padi females [ 38 ] and after the change of host plant in C. tujafilina [ 37 ]. β-glucosidase activity is strongly associated with the chemical composition of the host plant.…”

Climate change, and in particular the increase in temperature we are currently observing, can affect herbivorous insects. Aphids, as poikilothermic organisms, are directly exposed to temperature increases that influence their metabolism. Heat stress causes disturbances between the generations and the neutralization of reactive oxygen species (ROS). The aim of this work is focused on explaining how the aphid, using the example of Aphis pomi, responds to abiotic stress caused by temperature increase. The experiment was carried out under controlled conditions at three temperatures: 20, 25, and 28 °C. In the first stage, changes in the activity of enzymatic markers (superoxide dismutase (SOD), catalase (CAT), glutathione S-transferase (GST), β-glucosidase, polyphenol oxidase (PPO), and peroxidase (POD)) were determined in aphid tissues, at each temperature. In the second stage, microcalorimetry monitored changes in heat emitted by aphids, at each temperature. Our results showed that A. pomi defense responses varied depending on temperature and were highest at 28 °C. The flexible activity of enzymes and increase in the metabolic rate played the role of adaptive mechanisms and ran more effectively at higher temperatures. The A. pomi thus protected itself against ROS excessive induction and the aphids were able to respond quickly to environmental stress.

“…S. avenae is a monophagous and monoecious insect infesting a large array of plants of the family Poaceae (Gao and Liu, 2013;Li et al, 2013;Svobodová et al, 2013), whereas the life cycle of oligophagous R. padi involves seasonal migration between two groups of taxonomically distant host plants. The primary hosts of R. padi are a few members of the genus Prunus, and the secondary hosts include a broad range of cereals and grasses (Stoetzel and Miller, 2001;Aslan and Uygun, 2005;Łukasik 2009;Coulette et al, 2013).…”

We measured the total chlorophyll (Chl a+b) content in seedling leaves of fifteen maize cultivars infested by two studied aphid species (oligophagous Rhopalosiphum padi L., monophagous Sitobion avenae F.) 7 and 14 days after the beginning of infestation, using a SPAD-502 chlorophyll meter. Chlorophyll loss was more severe in R. padi-infested than in S. avenae-infested plants. Chlorophyll depletion was greater after long-term (14 days) than after short-term aphid infestation in the investigated host systems. Seedlings of Złota Karłowa and Tasty Sweet were more damaged by aphid feeding; Ambrozja and Płomyk plants were less damaged by aphid feeding.K Ke ey y w wo or rd ds s: : Total chlorophyll (Chl a+b) content, SPAD units, maize, Rhopalosiphum padi, Sitobion avenae.
